My fob started to act up the other day and now I can't seem to get it to push button start the car (key not detected) or unlock the doors. Mine is less than 2 years old but I'm suspecting the battery since my other remote seems to work ok so far. I'd like to try changing the battery. Does someone have instructions on how to do so?

Thanks.

 

I'm sure dodgecares will chime in... Sounds like the battery in the fob but never changed one myself.

 

CAUTION:
Do not touch or disturb the metal contacts for the battery. Avoid touching the new battery. Battery contamination from oils on your skin may result in shortened battery life. If the battery or contacts are contaminated, clean them thoroughly with rubbing alcohol.

1. Unlatch and remove the emergency key from the storage slot of the FOB with Integrated Key (FOBIK) case .
   
2. With the front of the FOBIK case facing downward, insert the tip of the emergency key into the notch between the case halves and twist the key to unsnap and separate the front case half from the back case half.
   
   
3. Lift the battery out of the receptacle in the back half of the FOBIK case .
   
4. Replace the battery with a recommended replacement battery.
   
5. Install the new battery into the receptacle in the back half of the FOBIK case with the negative terminal facing upward.
   
6. Align the front half of the FOBIK case with the back half.
   
7. Using hand pressure, squeeze the two FOBIK case halves around their perimeters until they snap back together.
   
8. Reinsert the emergency key into the storage slot of the FOBIK case.
   

Test the FOBIK operation.

 

Bought a new battery ($6.99 for a 2 pack), and all is well again. And just in case anyone is interested, my old key with the weak battery was still able to send signals occasionally to the car, like open the hatch or something, but was not able to start the car. Maybe the communication necessary for something as important as starting has to be stronger. I had a little bit of trouble getting the key fob back together, but that was about it.

My second key fob worked fine, but I like my "own" key. It's a moot point these days since it never comes out of your pocket, but back in the day your primary key got a little worn down and was the easy one to use all the time because of that :-)

 

Or in plain English, using logic and your eyes, pop that baby open, replace the battery, and put it back together.

 

I actually found it easier to open the fob with a small flat knife rather than the internal key, but be careful because there's a rubber gasket in there.
